Tatti sentenced Barr, now 22, to life in prison on a charge of second-degree murder with a firearm for the death of Dukes. Part of the reason Barr received that punishment is because he's a prison re-offender.

Before the sentencing, Barr, wearing a Marion County Jail uniform and handcuffed, decline to comment. Unlike Thursday, when Barr made hand gestures and shouted something after jurors found him guilty, he was calm.

While on the stand, Buie thanked the prosecutor, Bryon Aven, for"'putting up with her," the judge for "being fair," and God for guiding her.

Barr's lawyer, Eneid Bano of Orlando, declined comment.

Aside from the murder charge, Barr was also charged with possession of a firearm by a convicted felon. On the day of jury selection, which was Monday, Barr entered a no contest plea for for culpable negligence exposure to harm. He was adjudicated guilty and sentenced to 60 days.

It wasn't the only time Barr has been in trouble. Marion County Jail officials said they were transporting inmates to a hearing on Sept. 11 when Barr and two other inmates were involved in a fight. A fourth inmate was seen trying to separate the inmates from fighting.

Barr and the other two inmates involved in the scuffle returned to the jail to be checked by medical personnel. Two of the inmates seen by a nurse had minor injuries, according to a jail report. Barr refused to be seen and was sent to his housing area.

A jail investigator was unable to determine who started the altercation, as Barr and the other two inmates refused to give statements. The investigator noted he did not want to interview the inmate seen breaking up the fight because he has a habit of not telling the truth on several occasions, the report states.
